The request
“Our old theme had a checkbox in both the mini cart and cart page saying Allow Substitute Products. The new theme doesn't. We need it back.”
A small feature with real operational value.
The approach
We added the substitute products checkbox to the cart drawer and cart page on the new theme, with the customer's choice recorded on the order.
What we shipped
Substitute products checkbox in the cart drawer
Same checkbox on the cart page
Choice recorded on the order
